On my way back from home to Nijmegen, I transfered via Frankfurt Hbf onto a ICE train heading to Amsterdam. As I was walking along to tracks, heading to my wagon, I found from the corner of my eye that something was amiss. The livery, read strip on white background, had a new feature --- the Dutch NS logo.

I was very surprised by this, it seems though that DB and NS have a deal whereby the train along the Amsterdam route is operated by NS. A kind of code-sharing action like seen with flights. Onboard there were no further indications of this, all the staff wore DB uniforms.
